Phys.org / Experiment relies on pulsars to probe dark matter waves
Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. ...
Medical Xpress / Measles exposures reported in DC, Disneyland, as virus activity drops in Europe
Attendees of the National March for Life rally in Washington, DC last month may have been exposed to measles.
Phys.org / Nature's 'engine is grinding to a halt' as climate change gains pace, says study
Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats ...
Phys.org / China's emissions policies are helping climate change but also creating a new problem
China's sweeping efforts to clean up its air have delivered one of the biggest public health success stories of recent decades. Since the Air Pollution Prevention and Control Action Plan was launched in 2013, coal-fired power ...
Medical Xpress / Northern California reports first measles outbreak since 2020
California reported its first confirmed measles outbreak since 2020 on Feb. 10. The highly contagious disease infected 2,276 people nationwide in 2025, according to the Centers for Disease Control and Prevention. So far in ...
Phys.org / New record of great white shark in Spain sparks a 160-year review
On April 20, 2023, a juvenile great white shark (Carcharodon carcharias) measuring approximately 210 cm and weighing between 80 and 90 kg was incidentally caught by local fishermen off the coast of the eastern peninsula within ...
Phys.org / Promise the Earth: Why real climate action means restraint
A new book by a Cambridge engineer and an Oxford theologian argues that our faith in technology to solve the climate crisis is distracting us from the uncomfortable truth: that saving the planet is neither a task for future ...
Medical Xpress / Smokefree generation law could see English smoking prevalence drop below 5% decades earlier than expected
New research, led by experts at the University of Nottingham, has found that smoking prevalence among 12- to 30-year-olds in England could drop below 5% decades earlier than expected, if the government progressively raises ...
Phys.org / The 'Little red dots' observed by Webb were direct-collapse black holes
The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how the universe has evolved ...
Phys.org / Pulsar timing hints at a nearby dark matter 'sub-halo'
A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar neighborhood. Reporting their findings in Physical Review Letters, a team led by Sukanya Chakrabarti ...
Phys.org / Scientists discover 'levitating' time crystals that you can hold in your hand
Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create commercial or industrial ...
Phys.org / Social media feeds: Algorithm redesign could break echo chambers and reduce online polarization
Scroll through social media long enough and a pattern emerges. Pause on a post questioning climate change or taking a hard line on a political issue, and the platform is quick to respond—serving up more of the same viewpoints, ...
